Filed Oct. 4, 1965, Ser. No. 492,802 Claims. (Cl. 222-534) The inventionrelates broadly to closure caps for containers and more particularly toa dispensing closure cap having frangible sealing means.

Conventional dispensing closure caps include at least one part which maybe moved relative to another part in order to obtain a sealing action.One method of such sealing is found in US. Patent No. 2,793,795. Whilethis sealing action is obtained, the sealing accomplished is notpositive particularly for containers containing liquids such as lighterfluid and the like.

It is an object of the invention to provide a dispensing closure caphaving a valving spout member and a frangible sealing member which isremoved by a single movement of the valving spout member, the valvingspout member continuing to be operable.

It will not be here attempted to set forth and indicate all of thevarious objects and advantages incident to the invention, but otherobjects and advantages will be referred to in or else will becomeapparent from that which follows.

The invention will appear more clearly from the following detaileddescription when taken in connection with the accompanying drawings,showing by way of example a preferred embodiment of the inventive ideawherein like numerals refer to like parts throughout.

In the drawings forming part of this application:

FIGURE 1 is a perspective view of the dispensing closure cap of thisinvention in open position with the frangible sealing member shown asremoved.

FIGURE 2 is an exploded perspective view of the cap of FIGURE 1 with thesealing member intact.

FIGURE 3 is a sectional view on the line 44 with the cap in a closedposition.

FIGURE 4 is a sectional view on the line 44 of FIG- URE 1.

Referring to the drawings in detail, the dispensing closure cap Aincludes the base portion formed of the internally threaded annular wall12 and the circular top wall 13. Formed on the top wall 13 is theextension portion 14 in which is formed a semi-cylindrical cavity 16,which is in alignment with a diameter of the top wall 12. Leadingradially from the cavity 16 is the channel 18 which is parallel to the.top 12 and which extends to the edge of the top itself.

The cavity 16 is formed by the semi-circular wall 20 formed in the capextension portion 14 which terminates in an upper stop shoulder edge 22and at its lower edge at 24 where it joins the bottom of the channel 18.

Further provided are the pair of spaced wall members 26 and 28 formed inthe extension portion 14 which extend from and at right angles to theshoulder 22 and normal to the axis of the semi-cylindrical cavity 16.The wall 26 has formed on the upper edge thereof the semicircularbearing opening 30 which extends slightly greater than 180 and forms theslot 32. The wall 28 is similarly formed with the semi-circular bearingopening 34 which extends slightly greater than 180 and forms the slot36.

The numeral 38 designates the spout which includes the arm portion 40.The art portion 40 has formed on the lower end thereof the cylindricalbase portion 42, and extending axially of the spout base portion 42 arethe trun- 3,318,494 Patented May 9, 1967 nions 44 and 46. The baseportion 42 has extending radially thereinto the recess 48. Extendinglongitudinally through the arm portion 40 of the spout 38 and throughthe base portion 42 is the outlet passageway 50 which bypasses therecess 48.

The wall 20 has extending therethrough the outlet hole 52 which issealed at its inner end by means of the plug 54. The plug 54 is'attached at its lower end at the entire periphery thereof as at x by athin frangible connection with the inner surface of the wall .20 inalignment with the outlet hole 52. Thus, with the plug 54 in place,material cannot flow through the spout. Thus leakage is not controlledby the close fit of the base 42 in the cavity 16.

The spout 38 is pivotally mounted on the cap A by forcing the trunnions44 and 46 thereof through the slots 32 and 36, respectively, into thebearing openings 30 and 34, respectively. The trunnion 44 and 46 areheld in the bearing openings 30 and 34, for the openings extend morethan and the walls in which the bearing openings are formed are formedof plastic which is slightly deformable.

The base 42 of the spout 38 is forced into place in the positionshown inFIGURE 3 with the plug 54 extending into the recess 48. When the spout38 is pivotally moved from the position of FIGURE 3 to that of FIGURE 4,the plug 54 is broken away from the wall 20 at connection x by means ofthe wall portion 56 of the recess 48 contacting and being forced againstthe plug. The wall portion 56 is substantially normal to thelongitudinal axis of the passageway 50. As the plug 54 is severed, it iscarried captive from the outlet hole 52 and within the recess 48 by theturning moment of the recess 48 and the wall 56 thereof to a point inline with the channel 18 where the plug 54 is easily removed from therecess. The recess 48 is so positioned relative to the outlet hole 52that when the recess 48 is in substantial alignment with the channel 18,as in FIGURE 4, the passageway 50 is in alignment with the outlet hole52 whereby the contents of a container (not shown) attached to cap A canflow outwardly through the spout 38. The cap A is closed by returningthe spout 38 to the position of FIGURE 3 without the plug 54.

The invention is not to be understood as restricted to the details setforth since these may be modified within the scope of the appendedclaims with-out departing from the spirit and scope of the invention.
